Answer:
one solution
Step-by-step explanation:
3x - 4y = -35
3x + 4y = 5
6x = -30
x = -5
3(-5) + 4y = 5
-15 + 4y = 5
4y = 20
y = 5
(-5, 5)
The system of equations has one solution (-5.5) which is correct option (A).
What is the equation?
The equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
What is linear equation?
A linear equation is defined as an equation in which the highest power of the independent variable is always one.
Given the system of equations as :
3x - 4y = -35
3x + 4y = 5
Addition the both equations
3x - 4y + 3x + 4y = -35 + 5
6x = -30
Divided by 6 both the sides,
x = -30/6
x = -5
Substitute the value of x =2 in the equation 3x + 4y = 5
So, 3(-5) + 4y = 5
-15 + 4y = 5
4y = 20
Divided by 4 both the sides,
y = 20/4
y = 5
So, It has one solution x = -5 and y = 5
Hence, the system of equations has one solution (-5.5).
